I have used the traditional bleach method to disinfect my 1995 Prevost Country Coach fresh water system and struggled getting all the chlorine taste and smell out of the system afterwards. I know that sanitizing detergents are even harder to get flushed out of the system. As a result, I found myself not disinfecting my fresh water system and carrying bottled drinking water around all the time. Then I tried a new portable device called the King's Aqua Pure which was amazingly easy. It is portable, requires no plumbing, and only takes about 10 minutes of effort to disinfect my fresh water system. Plus it deodorized the system so that even my fussy kids would drink the water. Since it was so easy to use I started disinfecting my water system every time I filled it since you never know what is growing in your fill hoses.
